Global warming starts with the greenhouse effect, which is created by the relationship between the radiation from the sun and the Earth's atmosphere. Human activity also introduces specific types of gases into the Earth's atmosphere. As of 2005, as a result of these circumstances, over the last 50 years, the average global temperature of the Earth has experienced the fastest growth rate in history.

As of 2005, coal-burning power plants create the largest source of CO2 pollution in the United States, producing more than 2 billion tons of pollution annually. As of 2005, automobiles create the second largest source, which produces about 1.5 billion tons of carbon dioxide pollution annually. Global warming is a multi-faceted phenomenon that will have severe consequences if current trends continue. Melting glaciers, rising sea levels, warmer sea surface temperatures and habitat disruption are all consequences associated with global warming.

Modern technologies has begun to curb the effects of global warming. Technological advances allow vehicles to run cleaner while burning less gas. Power plants have also begun to generate electricity using non-polluting sources.
